Recently, we have identified the ubiquitin conjugate, protein phosphatase inhibitor 1 (I1), from postmortem muscles. Since I1 is one of the important regulators of glycogen metabolism, the effect of this conjugate (Ub-I1) present in postmortem muscle on glycolysis was investigated. Two sample groups were distinguishable: those not containing Ub-I1 (I, n=5)and those containing Ub-I1 (II, n=27). Due to the enormous variation in ultimate pH at 48 h postmortem, the latter group was subcategorized into a IIa group showing lower or normal pH and a IIb group showing higher or dark, firm, dry meat pH. Postmortem glycolysis occurred rapidly and vigorously among group I samples. The rate and extent of postmortem glycolysis was typical in group IIa samples while it... |
